This multi-impact helmet from S-One is one of the best fitting and safest helmets for skateboarding, longboarding, BMX and Roller Derby. The Lifer Helmet is a Dual Certified Helmet which means it is ASTM Certified to protect your head from multiple low impacts and CPSC Certified to protect your head from a single high impact.
Certified "multi-impact" means it is up to 5x more protective than the soft foam non-certified helmets.
High Impact ABS Outer Shell - Hard-Shell construction sets the standard for what a tough, reliable helmet is meant to be and is characterized by bonding an injection molded ABS shell to a layer of impact absorbing EPS foam. The lightweight EPS forms the inner layer of the “Hard-Shell” and is the primary component that crushes during impact to absorb and dissipate energy. Cradling the EPS is an injection molded ABS “Hard” Shell that protects the EPS from dings and nicks.
Deep Fit Design - Sit low on your head for a comfortable fit, protective fit.
CPSC 1203 Certified (USA - Skate/Bike) - Meets the skate and bicycle helmet certification standards of the Federal Consumer Product Safety Commission. Designed to withstand a single high impact or multiple low impacts.
ASTM F1492 Certified (USA - Skate/Roller) - Meets the certification standards of the American Society for Testing and Materials to withstand multiple impacts in non-motorized recreational sports such as skateboarding and roller skating.
CE EN 1078 Certified (Europe - Skate/Bike) - Meets the current European certification standards to withstand a single high impact and a variety of puncture impacts in non-motorized recreational sports such as skateboarding and biking.
